Go NO-Go

Today on the way home from work my truck was suddenly having, like a burst of power. The best way I can explain it is: like in the arcade racing games when you hit the "nitro," it would suddenly just take off and run. I have been hardly driving it till last week (no its winter here) and I haven't recently fixed anything. So any thoughts would be nice.


Also on a side note my Battery light is on. I have 3 good batteries and a on board battery charger that I plug in every night so the batteries should be mostly charged all the time. This isn't causing any problems other than my curiosity.

Thanks Again

How much fuel is in the tank? Sounds like the air in the fuel going to the IP.

I have no idea, the fuel guage dosen't work. I just switch tanks if it starts to run out. I have an electric fuel pump which helps that situation a bit.

Battery light is probably an indicator of alternator issues. Check the voltage while running for starters.

AIR an electric pump will suck air as well as a mechanical one. Your problem is between the e-pump and the tank. It is possible that your filter is stopped up, or your ip is on it's way out, but I would suspect air.

I hope its not the IP, I just put that on last fall and its only got maybe 500 miles on it.

I just thought of this: tonight when I got home I left the fuel pump running and bled the schrader valve and got a little burp of air. But I haven't bled it in forever.

The voltage should be the same pretty much everywhere, but the battery is the best place to check. If you have a voltmeter, check it while its not running and when it is. It should be around 12 with engine off and 13-14.5 or so running. You may need to raise the rpms a little to see full voltage.
